UNITED STATES WILLIAM J. HEWITT, OF BLOOMFIELD, NEW JERSEY.

WINDOW-SCREEN.

Application filed January 18, 1919.

To all whom it may concern.

Be it known that I, \VILLIMI J. Hnwrr'r, a citizen of the United States, residing at Bloomfield, in the county of Essex and State of New Jersey, have invented an Improvement in \Vindow-Screens, of which the following is a specification.

This invent-ion relates to a window screen and more particularly to a full length window screenadapted to be used on the inside of a window. I am aware that heretofore various forms of full length inside window screens have been proposed, but in all in stances of such which have come to my knowledge, no provision has been made for so constructing the screen as to permit of the usual use of the window shade by mounting the same in brackets attached to the inner faces of the window casing, nor has any provision been made in this type of window screen so far as I am aware by which the screen and parts thereof maintain themselves in position in the window casing. The object of my present invention therefore is to provide a window screen so constructed as to make itpossible to employ the window shade in the usual manner and also preferably to so construct the window screen that it automatically maintains itself in position in the window casing. Another object of my resent invention is to associate with the ful length window screen, devices by which the window shade or other covering may be secured to the window screen in such a manner as to provide a pocket for a layer of air between the window sashes and the screen with its covering, whether this covering be the window shade or not, and in this way as will be understood to make an insulator and thus assist inheating a room in which the window screens are used to form a space for non-circulating air. The window screen made in accordance with my invention will be hereinafter more particularly described.

In the drawing:

frame of the window screen to maintain the same in position.

Fig. 5 is a partial cross-section and elevation of the upper end of the window screen showing the offset part thereof.

Fig. 6 is an enlarged section on line 66, Fig. 1, and

Fig. 7 is an enlarged elevation illustrating the use of the clasp devices for holding the window shade.

Referring to the drawing, the window casing illustrated comprises a base board 10, side or upright members 11 and 12 together with the top cross member 13. The window screen includes a frame comprising a lower cross rail 14, side or upright rails 15 and 16, and a top cross rail 17 together with a central cross rail 18. On the outer side of the frame and associated with the side or upright rails 15 and 16 there are molding uprights 19. A similar molding cross piece 20 is associated with the top rail 17 and a molding piece 21 is similarly associated with the central cross rail 18. There is also a molding cross piece 22 extending between the upright side rails an appreciable distance above the bottom rail 14. 23 also designates a molding cross piece extending between the upright side rails 15 and 16 an appreciable distance above the central cross rail 18. Between the top cross rail 17 and the molding member 20 and also between the adjacent portions of the upright side rails 15, 16 and the molding uprights 19-there is secured a screen member 24 which as willbe understood may be made of woven wire cloth or other similar material, and the lower edge of which is also suitably attached to the molding member 23. Similarly between the central cross rail 18, and the mold ing member 21 as well as the adjacent parts of the upright side rails 15 and 16, and the molding uprights 19, there is a screen member 25, thelower edge of which is suitably attached to the molding cross piece 22.

In the lower portion of the frame, I prefer to employ a slide frame 26 in which there is also secured a screen member 27. The sides of the slide frame 26 are provided with tongues which fit into and are movable in grooves 28 provided therefor in the adjacent edges of the upright side rails 15 and 16, it being understood that this slide frame is movable to gain access to the lower window sash, and if desired may be further fitted with a removable panel of glass or other material indicated at 23 for ventilating purposes. In order to gain access to the upper sash, I may also employ a slide frame 29 similar to the slide frame 26, the slide frame 29 being fitted with a screen 30 and the sides thereof provided with tongues fitting into and movable in grooves 31 provided therefor in the upright side rails 15 and 16. As will be understood, the grooves 28 and 31 may be continuations of one another.

In order to have the screen self-maintained in position in the window'frame as well as to so construct the window screen as not to interfere with the window shade, the upper end of the window screen is provided with. an offset portion which will now be described. At the upper end of the window screen, both upright side rails thereof are provided, with offset longitudinal rails indicated at 32. These rails terminate at the top of the cross piece'17. Secured to each offset longitudinal rail 32 and extending appreciably above the same is an outside rail 34 and connected to and extending between the upper ends of the outside rails 34 is a cross rail 35. The upper end of each offset rail 32 is recessed on the inner side thereof as indicated at 36, and each outside rail 34: is recessed longitudinally as indicated at 37 providing a rib 38 thereon. This offset portion of the screen frame at the upper end thereof may be fitted with a paned made of screen material orotherwise as indicated at 44L in Fig. 2.

Associated with the parts of the window screen as hereinbefore described, I also em: ploy longitudinal stop rails 39nsuitably con nected to the faces of the side members 11 and 12 of the window casing as well as the cross rail 49 which rests upon the base board 10 "and extends between the longitudinal stop rails 39. The rails 39 and cross bar 40 are so placed as to liejflush against the adjacent side of the lower window sash. At

its upper end, each longitudinal stop rail 39 is provided with a block forming a shoulder 4:1 and a strip extending above the same andbeing recessed as indicated at 412 so as to providea rib 43 therein. In fittingthe window screen to position as will now be apparent, thelframe is necessarily placed at an inclination to the window casing as indicated 1n dotted lines in Flg. 3 of the, drawing. In this position the upper offset end of the screenframe is passed below the shoulders d1 on the stop rails 39 and the ,recesses 36 are adapted to receive the blocks forming the shoulders ll in which position the ribs on the outside rails 34 fit nae the recesses in the extension of the longitudinal stop rails 39; that is the'ribs 38 fit into the recess 42 and similarly the ribs 13 fit into the recesses 37 while the cross bar 35 then abuts against the outer edge of the top rail or cross member 13. This as will be understood forms a closed joint between the offset upperportion of the window screen frame and the parts associated with the upper ends of the longitudinal stop rails 39, while the' manner in which the shoulders 4:]. of the blocks on the longitudinal side rails are recelved 1n the recesses 36 forms a lock or means for maintaining the window screen In operatmg the window screen as hereinbefore described, the upper window sash is first lowered and then the upper end of the screen is passed through the window opening immediately below the shoulders 4C1 at the upper ends of the 'stop rails 39 with the screenin an inclined position.

tween the outer edges'of the offset rails-32 and the outsiderails 34 is such as to permit these parts to pass between theinner faces of'the stop rails 39. After the screen has been placed in this inclined position, the

shoulders or blocks ii are received in the ref cesses 36 provided therefor in the inner side of each of the oil'setrails 32and the screen frame permitted to swing to its normal position in which the side and bottom rails of the screen frame ab'ut' against the stop rails 39 and 40, and the extensions of the outside rails 3 1 abut against the strips comprising the ribs 4E3 and the recesses 42 so asto -con1-1 pletely cover the exposure or opening of the window casing, andat the upper end permit of sufficijent' space to employthe window shades in the usual-mannerby"mounting the same in the brackets 4J6 fixed on the inner faces of, the window casing. Of course as will be apparent, the reverse operation 18 necessary Hi removing thewindow screen It will be understood, of course, that the distance'be from the window casing, It will also be apparent that after the screen is in position the slidable member or screen 30 may be opened to gain access to the upper window sash and the lower slidable screen 27 may be moved to gain access to the lower window sash. 1

Associated with the window screen frame, and preferably attached to the inner faces of the upright side rails 15 and 16 thereof and in. suitably spaced positions, I prefer to employ a series of clamps or clasp members each consisting of a base 4:7 connected to;t he upright side rails anda spring actuated pivoted arm 4:8 adapted when the" shade is pulled to engage the edges thereof so as to maintain the window "shade in position relatively to the window screen and thus provide a pocket between the window screen and the window sashes. As will be apparent, however, these clasp members are equally well adapted to engage the edges of any suitable cover which may be employed instead of utilizing the window shade for the purposes indicated.

As herein shown and described, the upper offset end of the window screen is made an integral part of the window screen itself. It will be understood however, as within the spirit and scope of my invention to make this upper offset end of the screen a separate member and fix it permanently in the win dow casing for the purposes specified; that is, so as to mount the window shade in the usual manner in brackets secured to the inher faces of the window casing. And furthermore, that whether made as an integral partof the window screen or separately and permanently fixed in the window casing, this upper offset end of the frame may contain a panel of any suitable material, because in some instances, a netting may be advantageously used and in others, a sheet of fabric or even a panel of solid inflexible material.
